I would recommend the Tektronix AM502 if you can find one  - an excellent 
unit. The TM501 mainframes are quite numerous, and are quite inexpensive - 
also the TM503, some of these were on offer from a European dealer recently.
Good luck.

Hello Mark.

Yes, the AM502 is the thing I am searching, but they are not very cheap for
a 1977 vintage, in particular adding the mainframe.

It's possible that in 38 years no maker did anything like?
Looking better, all other modules I saw aren't equipped with front panel 
because are in effect vertical oscilloscope amplifiers and thus the output 
on the backplane. And they are not cheap also.

Best regards,
